National Weather Service Loses the Rain

For a few days the Sunday forecast called for "chance of rain." Then in the last 24 hours it was downgraded to "slight chance of rain." Now? No mention of rain whatsoever. That said, it'll be near freezing at the start and the first hour or two of the race will likely see temperatures remaining below 40F. Also, it looks like some chilly winds will be coming out of the north-northwest, sustained around 5 mph. About two-thirds of the course goes west, the other third south. So those winds might be a bit bothersome at times, but shouldn't be head-on, and might at times be at our backs. That's a trickier call right now than precipitation; we'll follow the forecasts closely over the next two days to see how the wind possibilities develop.

The current NWS forecast:
Early morning in Folsom: Partly cloudy, with a low around 33. North northwest wind between 5 and 7 mph.
Sunday in Sacramento: Partly sunny, with a high near 52.
